Digital Inclusion Resources

Improving The User Experience for People With Speech Difficulties

Written by Jeffrey Howard | Sep 19, 2025 11:00:00 AM

While digital innovations have revolutionized how people interact with the online world, the proliferation of new technologies, including artificial intelligence (AI) and voice-based applications, as well as communications technology, has had unintended consequences for professionals with disabilities.

The technology’s impact on people with speech and language disabilities is of immediate concern when it comes to the continued integration of voice-based software tools. Voice recognition programs, along with automated chat boxes, helplines, and hands-free programs and web applications, for example, are often exclusionary, as with many other aspects of digital life.

Digital ecosystems—including websites, apps, AI tools, and associated programs—need to be designed with everyone in mind. A lack of inclusive web principles not only limits your ability to reach as many customers as possible, but also gives the impression that you’re uninterested in accessibility best practices.

Not only is this bad business, but, more importantly, it disregards the moral imperative to design systems so that all people can enjoy the benefits of online experiences—regardless of whether they live with blindness or low-vision, deafness or are hard of hearing, physical disabilities, mental health challenges, speech and language disorders, learning and cognitive disabilities, or any other disability.

Key Takeaways

  • Voice-first isn't inclusive-first. As AI and voice-based tools proliferate, they're inadvertently excluding the 1.3 billion people globally living with disabilities—particularly those with speech and language disorders.
  • Retrofitting accessibility is expensive and frustrating for users. Alternatively, building it in from the start saves time, money, and builds trust with customers who rely on assistive technologies.
  • Simple alternatives make all the difference. Text-based chat options, keyboard navigation, word prediction software, and multiple communication channels ensure everyone can engage with your digital products.
  • Voice recognition software still struggles with ”non-standard voice patterns.” Whether from speech impediments, neurological conditions, or age-related changes, voice recognition software isn’t perfect, creating barriers that exclude valuable users and customers.
  • Web Content Accessibility Guidelines (WCAG) provide a roadmap. While not speech-specific, these standards emphasize alternative text, keyboard accessibility, adequate response time, and predictable navigation that benefits everyone.

Accessibility Cannot Be an Afterthought When Developing AI

In business terms, prioritizing accessibility expands your user base and market reach. It also helps your organization meet its moral responsibility to ensure everybody has access to fully participate in society, including the marketplace and suite of products and services that improve people’s lives.

This means centering accessibility during AI development, which has exploded during the past two years.

AI is growing at lightning speed, and unless companies build accessibility into the earliest stages of development, then roughly 1.3 billion people globally living with disabilities will be left behind.

Accessibility can’t be an afterthought.

Common Barriers to Voice Recognition & Screen Readers

An afterthought approach to accessibility is already experienced by those using assistive technology. Barriers to voice recognition and screen reader optimization are two examples.

“AI-powered tools often struggle with voice recognition accuracy for users with non-standard voice patterns, which are variations that can affect how readily others can understand someone,” explains Shlomit Shteyer, Director of Technical Program Management at Salesforce, a cloud-based AI CRM company. “Conditions like speech impediments, neurological disorders, or age-related changes can all affect someone's pattern of speech.”

Start With Accessibility

When tech companies discover accessibility issues later in the AI development process, projects are delayed, while large segments of the population are excluded.

“Most organizations realize they have accessibility issues during the testing phase or even after shipping, largely due to the fast-paced development cycle for AI tools,” she continues. “Identifying these issues late in the cycle can be costly in terms of time and resources, as it often requires significant rework and additional testing to address the problems.”

This not only raises AI development costs, but also harms your relationships with current customers who have speech and language difficulties and prevents you from reaching new ones.

“This delay can negatively impact user experience, particularly for individuals relying on assistive technologies, leading to frustration and reduced trust in the product,” she says. “As with any development process, identifying and addressing accessibility issues early is more cost-effective and ensures a more inclusive and user-friendly final product.”

Whether developing digital products or designing a website, you should conduct accessibility testing; your designers and programmers should be trained in inclusive design principles.

What to Avoid When Designing an Inclusive Digital Space

When designing a website or creating digital software or applications, inclusive design principles should always take center stage—which means avoiding features that exclusively rely on voice input. While voice input (speaking to a smart speaker, for example) can be convenient to some, you should also provide alternative methods of interaction for people to ensure people with speech and learning disabilities can communicate effectively.

For example, companies and websites utilizing telephone communication as the only means of directly interacting with an organization can impose unfair barriers on those who have difficulty expressing themselves verbally.

Digital Improvements & Design Elements to Help Foster Inclusion & Accessibility

The best way to help mitigate these obstacles is to provide alternative interaction and engagement options to voice inputs. Incorporating these elements can make a significant difference in overall engagement and accessibility, especially for people with speech and language disorders.

With that in mind, here are some specific design elements that will help make your site and content more accessible.

Text-based Communication

Typically, those with speech difficulties feel more comfortable with text-based services and applications, such as chat, e-mail, and feedback forms.

Augmentative & Alternative Communication

If verbal communication is required, those with severe speech difficulties can turn to Augmentative and Alternative Communication (AAC) methods. AACs comprise several communication methods that those with speech and language disorders can use to supplement or replace vocal communication.

One example is a Speech to Speech Relay Service, which enables those with speech difficulties to make a telephone call using their own voice, or an assistive voice device. These services use Communication Assistants to translate and relay messages between people.

Improving Voice Recognition

Speech recognition software enables phones, computers, tablets, and other devices to recognize and analyze spoken words, often using language as input to trigger a specific action. People with speech impairments can have difficulty using this technology, however, and while voice recognition software is improving, it can still present barriers for those who can’t express themselves verbally.

Utilizing Multiple Channels for Engagement

One near universal aspect of most websites is the ability to navigate pages with a keyboard. If you want to start incorporating voice-based tools, it’s important to include alternative navigation options so you don’t exclude people with speech and language disorders.

Word Prediction Software

For people who feel more comfortable communicating through text, word prediction software is useful for anticipating what a person is trying to type, reducing the number of keystrokes necessary for typing words.

Additional Web Design Considerations

  • If you’re incorporating timed features on your website, it’s important to provide everyone with enough time to respond. Along with providing people with adequate time to interact with content, you should also utilize time-out warnings and give users the option of an extension.
  • Allow users to interact with customer services through text-based chat, email or contact forms. Additionally, avoid unreliable tools, such as automated captions, subtitles and transcripts. When possible, generate this content manually to ensure accuracy.

Ensuring a more inclusive digital space will make your site and content more accessible and, as a result, will make your website more welcoming.

Website Design & Content Accessibility Resources

While there aren’t many accessibility guidelines that specifically address speech and language disorders, the Web Content Accessibility Guidelines (WCAG) are a valuable resource for maximizing usability for people with a variety of disabilities.

According to WCAG, all websites should:

  • Contain alternative texts for all non-text elements
  • Provide access to all functions from a keyboard
  • Include readable and understandable text content
  • Ensure site pages can be navigated in a predictable, consistent way
  • Allow users to correct any errors
  • Give users enough time to read text content
  • Make all video and multimedia elements accessible
  • Minimize the use of tables

Additionally, the international standards organization World Wide Web Consortium (W3C)’s Web Accessibility Initiative (WAI) is considering ensuring audio content has a text alternative.

Considering the needs of all groups, including people with speech and language disorders, will go a long way toward improving their user experience, and helping them feel more comfortable communicating and engaging in your digital spaces.
